The difference between laser cutting and laser engraving


Laser cutting machine adopts a new processing method and the characteristics of fast and flexible operation, replacing the traditional cutting method. Not only the price is low, the consumption is low, and because the laser processing has no mechanical pressure on the workpiece, so the effect, precision and cutting speed of the products are very good. It also has the characteristics of safe operation and simple maintenance. It can work continuously for 24 hours. The dust-free cloth and non-woven cloth cut by laser machine have the same size, no yellowing, automatic edge closing, no edge scattering, no deformation, no hardening. And it can cut any complex shape. High efficiency, low cost, computer design graphics, can cut any shape of lace of any size, the development speed is fast. Due to the combination of laser and computer technology, as long as the user designs on the computer, the laser engraving output can be realized, and the laser engraving can be changed at any time, and the product can be produced while designing. It can be used in leather, textile and clothing, metal cutting and other industries.


Laser engraving machine is produced by atomic transition and spontaneous emission. Although laser is light, it is different from ordinary light in that laser only depends on spontaneous emission for a very short period of time, and the subsequent process is completely determined by stimulated emission, so laser has a very pure color. Almost no divergent directionality. Engraving machine has high luminous intensity. At the same time, laser has high coherence, high intensity and high directivity. After the laser is generated, the laser is transmitted by the reflector and radiated to the processed object through the focusing mirror, which makes the processed object (surface) receive strong heat energy and the temperature increases sharply, which makes the point melt or vaporize rapidly due to high temperature. The purpose of processing can be achieved by cooperating with the running track of the laser head. The application of laser processing technology in the advertising industry is mainly divided into two ways: laser cutting and laser carving. For each way, we have some differences in the operation process. It is usually suitable for the engraving of wood, two-color board, plexiglass and other materials in the advertising industry.
